5. Argyresthia (Blastotere) albaureola , sp. nov. ( Figs. 17 , 88 , 145 , 201 )

Description. Adult ( Fig. 17 ) wingspan 9.0 mm. Head white, face tinged with golden. Labial palpus white, tinged with golden laterally. Antenna with scape white, pecten yellowish fuscous; flagellum white, ringed with grayish black. Foreleg with femur dark gray on inner surface, tibia and tarsus on inner surface and distal part of tarsus on dorsal surface blackish gray, remainder white; midleg yellowish white, tibia dotted with blackish gray dorsally near base and at middle, tarsus black distally on each tarsomere; hindleg grayish white, tarsus black on distal part of each tarsomere. Thorax white; tegula golden fuscous. Forewing ratio 4.0; ground color pale yellowish white; golden fuscous tinges below base of both costa and fold, with golden reflections under vertical light; costa with golden fuscous spots at distal 1/6 and before apex; golden fuscous spot at costa before middle, at middle of cell, and below basal 2/5 of fold, arranged in an obliquely inward line; dorsal fascia golden fuscous, from before middle of wing, extending obliquely outward to costal 2/3, somewhat golden from approximately anterior 1/5 or 1/4 to middle; golden fuscous spot at lower angle of cell, sometimes fused with costal spot at distal 1/6, smaller golden fuscous at tornus; termen with two ill-defined golden fuscous spots; apex blackish gray; cilia gray, golden fuscous at place of costal spots. Hindwing and cilia uniformly gray. Abdomen dark silvery gray dorsally, pale silvery gray ventrally.

Venation: Forewing with R4 and R5 stalked; hindwing with M3 and CuA1 stalked.

Male genitalia ( Figs. 88 , 145 , 201 ): Tuba analis shorter than width of valva. Socius covered with 18 scale-like setae, bearing a single seta posteriorly ( Fig. 201 ). Valva widest in basal 1/5, narrowed towards apex; transtilla short, triangular. Saccus short, triangular. Phallus straight, about 3.3 times as long as width of valva; cornutus about 1/2 length of phallus, with about ten strong denticles, shortening towards base and apex ( Figs. 145, 145 a). Second sternite with 10̄11 micro-setae in each row; eighth sternite Y-shaped. Coremata present.

Female unknown.

Type material. CHINA: Holotype, Ƌ, Hemu Village (47.71°N, 86.87°E), Buerjin County, Xinjiang Uygur Autonomous Region, 1114 m, 23.vii.2007, leg. Xinpu Wang et al., slide no. LTT12436 . Paratype: 1Ƌ, Qiongbola Town (43.44°N, 81.03°E), Chabuchaer Autonomous County, Xinjiang Uygur Autonomous Region, 1871 m, 2.viii.2007, leg. Xinpu Wang et al., slide no. LTT12030 .

Distribution. China (Xinjiang).

Diagnosis. This new species resembles A. (B.) cineretra . It can be separated from the latter by pale yellowish white ground color of the forewing, and in the male genitalia by the valva widest in the basal 1/5 and the straight phallus. In A. (B.) cineretra the ground color of the forewing is gray, the valva is widest in basal 2/5, and the phallus is arched or almost straight in the male genitalia.

Etymology. The specific name is derived from the Latin albus, meaning white, and aureolus, meaning golden, indicating the pale yellowish-white forewing with golden patterns.
